SUMMARY OF THE INVENTION

It is an object of the present invention to improve output of a beverage dispenser.

The object of the present invention is achieved by a method according to claim 1 and a beverage vessel according to claim 17.

The invention discloses a method of filling beverage into a portable beverage vessel comprising the step of selecting at least one beverage by the program running on a personal electronic device having a personal electronic device processor. The at least one beverage is represented by at least one beverage parameter set. The at least one beverage parameter set is stored in beverage data. Then, the beverage vessel is positioned in the proximity of the personal electronic device by the user.

In the context of the present invention positioning the beverage vessel in the proximity of the electronic device can be interpreted such, that the distance between the beverage vessel and the personal electronic device is smaller than approximately 5 cm, preferably smaller than approximately 3 cm, more preferred smaller than approximately 1 cm. The NFC communication may be a RFID communication. The radio range of the near field communication from antenna to antenna may be smaller than approximately 5 cm, preferably smaller than approximately 3 cm, more preferred smaller than approximately 1 cm.

The antenna of the personal electronic device starts emitting a RF field. In the next step the beverage data is transmitted by a radio message from the antenna of the personal electronic device to an antenna of the beverage vessel by near field communication (NFC) controlled by the personal electronic device processor by the personal electronic device by near field communication. Electric energy from the radio message and/or RF-field received by the vessel antenna is extracted. The electric energy may be stored in an energy storage device of the beverage vessel.

The step of transmitting the beverage data from an antenna of the personal electronic device in a radio message to an antenna of the beverage vessel by near field communication controlled by the personal electronic device processor by the personal electronic device by near field communication may comprise the step of emitting an RF field by the antenna of the personal electronic device.

Thereafter, the beverage data is stored in a memory of the beverage vessel controlled by the vessel controller after receiving the beverage data by the antenna of the beverage vessel. The vessel processor and the vessel memory are powered by the RF field received by the vessel antenna. The NFC communication may be a RFID communication.

The user positions the beverage vessel in the proximity of a beverage dispenser. The user may position the upper opening of the beverage vessel under a nozzle of the beverage dispenser. After the beverage vessel is detected in the proximity of the beverage dispenser the beverage dispenser transmits a request command from an antenna of the beverage dispenser to the antenna of the beverage vessel by near field communication requesting to transmit beverage data by a radio message. Electric energy from the radio message received by the vessel antenna is extracting. The electric energy in the energy storage device of the beverage vessel.

The step of transmitting by near field communication under control of a dispenser controller by the beverage dispenser a request command from the antenna of the beverage dispenser to the antenna of the beverage vessel requesting to transmit beverage data in a radio message may comprise the step of transmitting a RF field by the dispenser antenna. The vessel processor and the vessel memory are powered by the RF field received by the vessel antenna.

In response to receiving the request command by the beverage vessel, the beverage data is read from the memory of the beverage vessel and the beverage data is transmitted by the antenna of the beverage vessel to the antenna of the beverage dispenser by near field communication under control of the vessel processor. In response to receiving the beverage data by the antenna of the beverage dispenser, the beverage dispenser outputs at least one beverage defined by the beverage parameter set in the beverage data into the beverage vessel under control of the dispenser controller.

The beverage vessel may be a bottle, a carafe, a glass, a cup or the like.

The beverage vessel may comprise an impedance matching circuit coupled with the antenna of the beverage vessel. The impedance matching circuit ensures that an appropriate amount of energy is transferred from the antenna. The radio signal of the radio message induces an AC current in the antenna and impedance matching circuit. The AC current is rectified by a rectifier circuit to a DC power. The voltage of the DC power may be increased by a voltage multiplier. The DC power may be supplied to the vessel processor, the vessel memory or the like. The DC power may be stored in the capacitor. This process is known as energy harvesting.

The vessel processor is only powered by the radio message, if the vessel antenna is positioned in the proximity of the antenna of the personal electronic device or the antenna of the beverage dispenser. Thereby, it can be ensured that the personal electronic device communicates only with a single beverage vessel and powers only a single beverage vessel. Thereby, the method according to the present invention can determine that the beverage vessel is positioned in the proximity of the personal electronic device or the beverage dispenser.

The short range of the near field communication and/or power harvesting ensure that the personal electronic device and/or the beverage dispenser only communicate with a single beverage vessel.

The present invention has the advantage that the user can select a desired beverage before he positions the beverage vessel underneath the nozzle of the beverage dispenser. Thereby, the output of the beverage dispenser can be improved, since the user spends less time after positioning the beverage vessel in the beverage dispenser for selecting beverage. In prior art systems, the user had to position the beverage vessel underneath the nozzle of the beverage dispenser and select a beverage thereafter. This process was time-consuming and reduced the total output of the beverage dispenser.

In one embodiment the user may be requested by a user interface to press a start button, before the beverage is dispensed. In one embodiment the user interface may be displayed on the beverage dispenser. In another embodiment the user interface may be displayed on the personal electronic device. The personal electronic device may be coupled with the beverage dispenser by a near field network, such as RFID or Bluetooth, or any other suitable wireless network.

Since the selected beverage is stored in a memory associated with the beverage vessel the method according to the present invention does not require a permanent data connection to transmit a selected beverage from a personal electronic device to a remote server and to store the selected beverage on a remote server for retrieval by the beverage dispenser. Thereby, reliability of a beverage dispensing system can be increased significantly and the cost associated to the beverage dispensing system can be reduced significantly.

The beverage parameter set may be a list of parameters defining type and quantity of ingredients, such as minerals, flavors and the like, volume of beverage to be dispensed, set temperature of the beverage and/or set carbonization of the beverage.

The method may comprise the step of selecting a single beverage by the program running on the personal electronic device by the user, wherein the single beverage is defined by the beverage parameter set and wherein the beverage data comprises a single beverage parameter set selected by the user. The dispenser controller determines, whether the beverage data comprises a single beverage parameter set. After determining at the beverage dispenser under control of the dispenser controller that the beverage data comprises a single beverage parameter set, the beverage defined by the single beverage parameter set is output into the beverage vessel under control of the dispenser controller.

If the user selects only a single beverage by the program running on the personal electronic device, only a single beverage parameter set is stored in the beverage data. If the dispenser controller detects that only a single beverage parameter set is stored in the received beverage data, the dispenser controller outputs the beverage defined by the single beverage parameter set without any further interaction with the user. The user does not have to touch the beverage dispenser at all, which improves hygienic conditions. Further, output of the beverage dispenser is increased.

Alternatively or additionally the beverage data may comprise a plurality of beverage data sets selected by the user. In this embodiment a plurality of beverages may be selected by the program running on the personal electronic device, wherein each beverage is defined by the beverage parameter set. The dispenser controller of the beverage dispenser determines, whether the beverage data comprises a plurality of beverage parameter sets. After the beverage dispenser determines under control of the dispenser controller that the beverage data comprises a plurality of beverage parameter sets, the dispenser controller outputs on a user interface a plurality of graphical information each representing one of the plurality of beverage parameter sets. The user selects on the user interface one graphical information each indicating one of the beverage parameter sets. Under control of the dispenser controller the beverage defined by the beverage parameter set represented by the selected graphical information is output into the beverage vessel.

The present disclosure should in no way be limited to the exemplary implementations and techniques illustrated in the drawings and described below. As used in the description herein and throughout the claims, the following terms take the meanings explicitly associated herein, unless the context clearly dictates otherwise: the meaning of “a,” “an,” and “the” includes plural reference, the meaning of “in” includes “in” and “on.” Spatial relationships like “above”, “blow” or the like are not to be interpreted limiting.

Reference is made to FIG. 1a showing a beverage dispenser 100 according to the present invention. The water dispenser 100 is connected to a water source 102 that may be tap water or a tank.

The water source 102 is connected by a conduit with a pre-filter 104 which may comprise a sediment filter and/or an activated carbon filter.

The pre-filter 104 is connected to a reverse osmosis filter 106 acting as demineralization device. The water drawn from the water source 102 is pressurized by a pump 105 before entering the reverse osmosis filter. Operation of a reverse osmosis filter 106 is known to the person skilled in the art, and therefore operation of the reverse osmosis filter 106 does not have to be explained in further detail. The concentrate, in which the undesired components, such as minerals, heavy metals or the like are solved, as well as filtered microorganisms are output to a drain 107.

The water (permeate) output by the reverse osmosis filter 106 is fed to a flow-type tempering device 122 forming a beverage preparation device. The flow-type tempering device 122 is tempering the water to a temperature set by a dispenser controller 136. The set temperature of the water to be output by the flow-type tempering device 122 is commanded by the dispenser controller 136. The water flows from an output of the flow-type tempering device 122 to the input of a flow-type carbonization device 124 adding carbon dioxide to the water as set by a dispenser controller 136.

From an output of the flow-type carbonization device 124 forming also a beverage preparation device, the water flows to a flow-type mineralization device 126 also forming a beverage preparation device. The dispenser controller 136 controls the mineralization device 126 such that the water output by the flow-type mineralization device comprises the minerals desired by a user.

The flow-type mineralization device 126 may comprise a plurality of vessels filled with mineralization fluid, wherein a plurality of micro metering pumps delivers the mineralization fluids in the respective desired quantity into the water flowing through an input of the flow-type mineralization device 126 to an output of the flow-type mineralization device 126. Such flow-type mineralization device is for example disclosed in the European patent application EP18207971.5, which is incorporated herein in its entirety by reference. The water flows from the output of the flow-type mineralization device 126 to an output valve 128 and passes through a retrograde contamination prevention device 130, such as a UV light source, before it is output by a nozzle to a portable beverage vessel 200. The portable beverage vessel 200 may be a glass, a cup, a bottle, a carafe or the like. The portable beverage vessel 200 may be suitable for carrying beverage for a single person or a small group of persons, such as 1 to approximately 10 persons. “Portable beverage vessel” in the context of the present invention means that the beverage vessel may be carried by a person, such as a waiter, nurse or a user.

All components of conduits, the flow-type tempering device 122, the flow-type carbonization device 124, the flow-type mineralization device 126, the output valve 128, the retrograde contamination prevention device 130 and the nozzle 132 are made of metal and/or glass that is biological inert. Also, the output port for permeate of the reverse osmosis filter 106 is made of biological inert material, particularly a biological inert metal. The biological inert metal may comprise stainless steel, VA steel, VA1 steel, VA2 steel, VA3 steel, VA4 steel or the like. A biological inert material is a material that does not serve as nutrition for germs, microorganisms, a biological film, bacteria, virus or the like. Germs cannot form on biological inert metal contrary to plastics. Thereby, germ formation and deposition of biological films are prevented.

In the beverage dispensing operation mode, the controller controls the pump 105 after a request of a user to dispense beverage such that in all beverage preparation devices 122, 124, 126 an equal flow rate is achieved.

The beverage dispenser 100 according to the present invention further comprises an user interface 138 such as a touch sensitive screen, by which the user may select the type of beverage and/or parameters of the beverage to be dispensed. The parameters of the beverage to be dispensed may comprise the temperature of the beverage, the carbonization of the beverage, the mineralization of the beverage, any type of flavoring agents or the like. The parameters may be individually selectable by a user or may be determined by predefined recipes or types of beverage displayed on a display. The recipe may be a reference to list defining type and quantity of ingredients or a list defining type and quantity of ingredients. The parameter may include an identification of a user who requests the beverage.

The recipes may be stored in a database 140 of the beverage dispenser 100. The user may select the appropriate recipe by the user interface 138. The recipe defines the type of beverage and parameters of beverage to be output.

Reference is made to FIG. 2. The portable beverage vessel 200 comprises a vessel antenna 206, a vessel transceiver 208, a vessel processor 210, a vessel memory 212 and a display element 204. A user may select on a user interface of a personal electronic device 250, such as a mobile phone, a smart phone, a tablet computer or the like a water recipe defining a beverage parameter set. Icons 252, 254 and 256 displayed on the user interface represent different water recipes and/or different beverage parameter sets. Each beverage parameter set may comprise a list of minerals, concentration of each of the minerals in the beverage, type and concentration of flavours, the volume of the portable beverage vessel, the volume to be dispensed in the portable beverage vessel, the set temperature of the beverage to be dispensed and/or the set mineralization of the beverage to be dispensed. As soon as the user has selected the desired water recipe 252, 254, 256, the user positions this personal electronic device 250 in the proximity of the beverage vessel, particularly in proximity of the antenna 206 of the beverage vessel. Preferably, the distance between the near field antenna 260 of the personal electronic device 250 is positioned at a distance of less than approximately 5 cm, preferably less than proximately 3 cm, more preferred less than approximately 1 cm from the vessel antenna 206. The communication protocol for transmitting information from the antenna 260 of the personal electronic device 250 to the vessel antenna 206 is a near field communication protocol, such as RFID. The antenna 260 of the personal electronic device 200 transmits a RF field for powering the vessel processor 210 and the vessel memory 212.

The near field signal may be an RFID signal, such as in the 125 kHz, 134 kHz or 13.56 MHz frequency band. The vessel antenna 206 is coupled with the vessel transceiver 208 demodulating the near field signal and extracting energy for supplying the vessel processor 210, the memory 212 and the display element 204 with energy (energy harvesting). The energy may be stored in a capacitor 213. The radio range of the near field communication from antenna to antenna may be smaller than approximately 5 cm, preferably smaller than approximately 3 cm, more preferred smaller than approximately 1 cm. In one embodiment, the NTAG 213/215/216 Forum2 at 13.56 MHz is used.

The beverage vessel 200 may comprise an impedance matching circuit coupled with the vessel antenna 206. The impedance matching circuit ensures that an appropriate amount of energy is transferred from the vessel antenna 206. The radio signal of the radio message induces an AC current in the vessel antenna 206 and the impedance matching circuit. The AC current is rectified by a rectifier circuit to a DC power. The voltage of the DC power may be increased by a voltage multiplier. The DC power may be supplied to the vessel processor 210, the vessel memory 212 or the like. The DC power may be stored in the capacitor 213. This process is known as energy harvesting. The vessel memory 212 may be an EEPROM. The vessel processor 212 and the vessel memory may be implemented on the same semiconductor device.

The RF field must be activated before any communication with the beverage vessel 200. After the RF field in activated the vessel processor 210 performs a power on reset. Thereafter, the vessel processor 210 listens for received message. The vessel processor 210 executes the commands in the messages, stores data in the vessel memory 212, reads data from the vessel memory and/or transmits data to the transmitter of the message received.

The vessel processor 210 is only powered by the radio message and/or the RF field, if the vessel antenna 206 is positioned in the proximity of the antenna 260 of the personal electronic device 250. Thereby, it can be ensured that the personal electronic device 250 communicates only with a single beverage vessel 200 and powers only a single beverage vessel 200. Thereby, the method according to the present invention can determine that the beverage vessel 200 is positioned in the proximity of the personal electronic device 250. For powering the vessel processor 210 the personal electronic device 150 must emit the RF field during the entire communication with the beverage vessel 200.

As soon as a transmit icon 258 is pressed, the processor of the personal electronic device 250 transmits via the antenna 260 of the personal electronic device 250 by near field communication the beverage data to the vessel antenna 206. The beverage data includes the beverage parameter set and an identification of the user of the personal electronic device 250 and a volume of the portable beverage vessel. The identification of the user can be input by the user or retrieved from the data are stored on the personal electronic device 250, such as the name of the personal electronic device, the name of the current user of the mobile electronic device 250 or the like.

The vessel transceiver 208 decodes the message received by the vessel antenna 206 and the processor 210 stores the beverage data received by the message from the personal electronic device 250 in the vessel memory 212. The beverage data received from the personal electronic device may include one beverage parameter set or a plurality of beverage parameter sets. After the beverage data is stored by the vessel processor 210 in the vessel memory 212 the user can carry the beverage vessel 200 to the water dispenser 100 shown in FIG. 1.

Reference is made to FIG. 1 again. If the dispenser controller 136 detects that the portable beverage vessel 200 is arranged in the beverage dispenser 100, the dispenser controller 136 requests the vessel processor 210 to transmit beverage data. The vessel processor 210 loads the beverage data from the vessel memory 212 and transmits the beverage data by the vessel transceiver 208 and the vessel antenna 206 to the dispenser antenna 148. The dispenser antenna 148 receives the beverage data and the beverage data is transferred by the dispenser transceiver 146 to the dispenser processor 136. The dispenser antenna 148 may emit a RF field for powering the vessel processor 210 and the vessel memory 212. The RF field must be emitted during the entire communication process between the beverage dispenser 100 and the beverage vessel 200.

The vessel processor 210 is only powered by the radio message and/or RF field, if the vessel antenna 206 is positioned in the proximity of the dispenser antenna 148. Thereby, it can be ensured that the beverage dispenser 100 communicates only with a single beverage vessel 200 and powers only a single beverage vessel 200. Thereby, the method according to the present invention can determine that the beverage vessel 200 is positioned in the proximity of the beverage dispenser 100.

In one embodiment the dispenser controller 136 may detect that the portable beverage vessel 200 is arranged in the beverage dispenser 100 by NFC.

The dispenser processor 136 analyses the beverage data. If the dispenser processor 136 detects that the beverage data comprises only a single beverage parameter set, the dispenser controller 136 retrieves the appropriate recipe from the database 140. In one embodiment, the beverage data may comprise a number, a reference, an index, a hash value or the like referring to the recipe stored in the database 140.

In one embodiment the dispenser processor 136 may instruct as described below the appropriate components of the beverage dispenser to generate beverage. In another embodiment the dispenser processor 136 may display a start button on the user interface 138 and commence preparing the beverage by instructing as described below the appropriate components of the beverage dispenser to generate beverage after the user has pressed the start button.

Thereafter, the dispenser controller 136 instructs as described above generation of the beverage. Particularly, the dispenser processor 136 instructs the pump 105 to pump an aqueous liquid through the reverse osmosis filter 106 to the tempering device 122. The dispenser controller 136 instructs the tempering device 122 to temper the aqueous liquid as defined in the beverage parameter set. The tempered aqueous liquid is passed to the carbonization device 124. The dispenser controller 136 instructs the flow-type carbonization device 124 to carbonize the aqueous liquid as defined in the beverage parameter data. Thereafter, the aqueous liquid is passed to the flow-type mineralization device 126. The dispenser controller 136 instructs the flow-type mineralization device 126 to mineralize the beverage as defined in the water recipe retrieved from the database 140 or in the beverage parameter set. Thereafter, the beverage is output into the beverage vessel 200.

Thereafter, the dispenser processor 136 instructs the vessel processor 210 to display beverage data on the display element 204. The displayed data may comprise the identity of the user, a representation of the recipe of the beverage dispensed into the portable beverage vessel 200, the amount of beverage dispensed into the beverage vessel 200, the date of dispensing, the time of the dispensing, the dispensed volume, the temperature of the beverage dispensed, the carbonization of the beverage dispensed, the total volume of beverage dispensed within a predetermined time span, the amount of saved one-way bottles or the like. In one embodiment the vessel controller 136 can transmit the data to be displayed on the display element 204 by near field communication to the vessel processor 208. In another embodiment, the dispenser controller 136 can request the vessel controller 208 to retrieve the necessary data from the vessel memory 212 and to display it on the display element.

The display element 204 may including, at least one LED, at least one OLED, a LED display, an OLED display, a display matrix, an e-paper, an electrophoretic e-paper, a liquid crystal e-paper, a bi-stable display, a bi-stable liquid crystal display. E-paper, electrophoretic e-paper, the bi-stable display and the bi-stable liquid crystal display have the advantage, that no energy is needed for displaying information on the display element, once the information has been updated on the display element 204. The information may be displayed as symbols, alphanumeric characters, colours, coloured icons or the like. If a single or small number of LED(s) or OLED(s) are used as display element 204, the information may be coded by the colour emitted by the LED(s) or OLED(s) and/or a flashing frequency of the LED(s) or OLED(s).

If the dispenser processor 136 detects during analysing the beverage data that the beverage data comprises a plurality of beverage parameter sets, the dispenser processor 136 instructs the user interface 138 to display a plurality of graphical symbols, such as a text, icons or the like, each representing one beverage parameter set. In one embodiment, the graphical user interface 138 may display the name of the water recipe associated with each beverage parameter set in the beverage data. The name of the water recipe can be stored in the data base 114 and retrieved by the beverage parameter set. Each beverage parameter stored in the beverage data can be one of the favourite recipe of the user.

The user may select on the user interface 138 one representation of a beverage parameter set as the desired beverage to be dispensed. Thereafter, the dispenser processor 138 continues to dispense the beverage as described above by instructing the appropriate components of the beverage dispenser 100 to generate the beverage, such as the pump 105, the reverse osmosis filter 106, the flow-type tempering device 122, the flow-type carbonization device 124 and the flow-type mineralization device 126.

In one embodiment, the dispenser processor 136 instructs the vessel processor 208 to display data about the selected beverage and/or beverage parameter set on the vessel controller 204 as well as to display information identifying the user. In one embodiment, the dispenser processor 136 transmits via near field communication a reference to the selected beverage and/or beverage parameter set. In another embodiment the dispenser processor 136 may transmit the beverage parameter set, namely at least one value of the beverage parameter set.

In one embodiment the beverage dispenser 100 is connected to a remote server 150. The dispenser controller 136 may receive new beverage recipes and/or beverage parameter sets from the remote server 150 and store the new beverage recipes and/or beverage parameter set in the database 140. The program running on the personal electronic device 250 can analyse the beverage consumption of the user as described above to generate usage data. The usage data may be stored in the beverage data. In one embodiment, a classification of the beverage preference of the user may be stored in the beverage data.

If the user positions the beverage vessel 200 at the beverage dispenser as described above, the vessel processor 208 may transmit the usage data via near field communication to the dispenser controller 136. If the dispenser controller 136 determines that the usage data matches to or corresponds with the recommended consumer types of the new beverage recipe and/or beverage parameter set, the dispenser controller 136 proposes the user the new beverage recipe and/or beverage parameter set on the user interface 138 to the user. The user may select the new beverage recipe and/or beverage parameter set as beverage to be dispensed. The dispenser controller 136 continues dispensing beverage as described above with the selected beverage parameter set. Further, the dispenser controller 136 and the vessel processor 208 to display the selected beverage parameter set on the vessel controller. Further, the selected beverage parameter set will be stored in the vessel memory as instructed by the dispenser controller 136 to the vessel processor 210.

If the user has not select the new beverage recipe and/or beverage parameter set to be dispensed after recommending it by the user interface 138 of the beverage dispenser 100, the dispenser controller 136 may ask the user by information displayed on the user interface 138, whether he wishes to consume the new beverage recipe and/or beverage parameter set later. If the user presses on the user interface 138 the appropriate symbol indicating that he agrees to consume the new beverage at a later time, the dispenser controller 136 instructs the vessel processor 210 to store the new beverage recipe and/or beverage parameter set in the vessel memory 212.

As soon as the personal electronic device 250 detects presence of the beverage vessel 200 by near field communication, the vessel processor 210 may receive the new beverage data and/or the new beverage parameter set and store it in the vessel memory 212. The personal electronic device 250 may display information about the new beverage data and/or the new beverage parameter set on the display of the personal electronic device 250.

In one embodiment the dispenser processor may activate the RF field emitted by the dispenser antenna 148 permanently to detect presence of the beverage vessel and send a message to a potential beverage vessel 200 for identifying the beverage vessel 200. In another embodiment the dispenser processor may activate the RF field emitted by the dispenser antenna 148 intermittently to detect presence of the beverage vessel 100. The vessel processor may activate periodically the RF field and send a message to a potential beverage vessel 200 for identifying the beverage vessel 200. If no response is received from a beverage vessel, the RF field is deactivated for a predetermined time span that may rage for example between 50 msec and 0.3 seconds. Thereafter, the vessel processor may activate again the RF field and send a message to a potential beverage vessel 200.

Reference is made to FIG. 1a showing a second embodiment of the beverage dispenser 100 and beverage vessel 200. In the second embodiment the dispenser processor does not output data on the user interface 138 of the beverage dispenser 100 but on the display of the personal electronic device 250.

On the upper side the vessel controller 202 an annular recess 220 is formed adapted to accommodate the pedestal portion 240 of the container 201. On the upper side of the vessel controller 202 a second magnetic element 228 is arranged. The second magnetic element 228 is arranged above the annular are recess 220 such that the first magnetic element 248 and the second magnetic element 228 are arranged as close as possible or contact each other, if the vessel controller 202 is coupled with the container 201 and the pedestal portion 240 is arranged in the annular recess 220. Around the second magnetic element 228 a flange 224 is formed essentially annularly and extending in the upper direction from the second magnetic element 228 and forming a recess 226 above the second magnetic element 228. If the vessel controller 202 is coupled with the container 201 the flange 224 is arranged around the first magnetic element 248 and supports aligning and securing the vessel controller 202 with the container 201.

At least one of the first magnetic element 248 and the second magnetic element 228 is a permanent magnetic element. It is also possible, that one of the first magnetic element 248 and the second magnetic element 228 is a permanent magnetic element and the outer magnetic element is a ferromagnetic element.

It is an advantage of the present invention that the vessel controller 202 can be easily coupled with the container 201 and released from the container 201. Further, performance of the beverage dispenser 100 is increased significantly, since the user needs to spend less time at the beverage dispenser 100 for selecting the desired beverage. Further, the present invention avoids use of one-way bottles, since each user can select the desired beverage by his personal electronic device. Less one-way bottles have to be transported and less storage space is required at the point of use such as an office, a gym, a bar, a hotel lobby, in a nursing home, rail stations, airports or the like.

In another embodiment the beverage dispenser may receive a request for beverage comprising the recipe and the volume of beverage to be output by a network interface 144. The network interface 144 may be a wireless network interface such as WLAN and/or a wire bound network interface such as an Ethernet interface.

The user and/or the beverage vessel 200 may be identified by the beverage dispenser, for example by communication with the beverage vessel 200. Therefore, the beverage vessel may comprise an RFID tag or any other device that is suitable for near field communication or mobile communication.

It is also possible that the user transmits his beverage order from a mobile device or any other computer via a network, such as a wireless network, to the beverage dispenser 100. The order may include the type of beverage, a recipe for preparing the beverage, a volume of beverage, the temperature of the beverage to be dispensed, the carbonization of the beverage to be dispensed or the like. Particularly, the beverage dispenser 100 receives information relating to the beverage comprising, but not limited to the type of beverage to be dispensed, an identification of a user, who requested the beverage, an identification of a location in a restaurant, a hotel or a meeting area to which the portable beverage vessel has to be carried, the volume of the beverage, the time stamp of the filling event, a parameter of the beverage to be dispensed, such as temperature, carbonization, mineralization, flavoring or other useful information for defining the beverage order. The dispenser controller 136 stores the information relating to beverage for preparing the beverage, and the dispenser controller 136 controls the beverage preparation devices 122, 124, 126 such, that beverage according to the information relating to the beverage is generated.

In a public environment, such as a restaurant, a bar, a hotel, a meeting room environment or the like a waiter or assistant may ask a plurality of users, which beverage they prefer. The waiter and/or assistant may forward the order of the users to the beverage dispenser 100, such as by a mobile electronic device (not shown) or by entering the order at the user interface 138. The waiter and/or assistant will receive order for beverage from a plurality of users, but the waiter and/or assistant cannot distinguish the beverage, as soon as the beverage is output to the user vessel. Particularly, the users may order different types of water having individualized mineralization. However, the assistant and/or waiter cannot distinguish the different individualized waters, as soon as they are dispensed into the respective portable beverage vessel 200.

Therefore, the assistant and/or waiter can add an identification of the user, who requested the beverage, to the order of a beverage to the beverage dispenser. Thus, the assistant and/or waiter has supplied the beverage dispenser 100 and the dispenser controller 136 with all required information relating to the requested beverage.

Therefore, the beverage dispenser 100 according to the present invention comprises a near field transceiver 146 operatively coupled with the dispenser controller 136. The dispenser controller and the near field transceiver 146 transmit information relating to the beverage comprising, but not being limited to the type of beverage in the portable beverage vessel, an identification of a user, who requested the beverage, an identification of a location in a restaurant, a hotel or a meeting area to which the portable beverage vessel has to be carried, the volume of the beverage, the time stamp of the filling event, a parameter of the beverage in the portable beverage vessel, such as temperature, carbonization, mineralization, flavoring or any other useful information relating to the beverage in the portable beverage vessel to the vessel controller 202 of the portable beverage vessel 200. The portable beverage vessel 200 comprises a vessel antenna 206, a vessel transceiver 208, a vessel processor 210, a memory 212 and a display element 204.

The near field transceiver 146 transmits a near field signal to the vessel antenna 206 of the portable beverage vessel 200. The near field signal may be an RFID signal, such as in the 125 kHz, 134 kHz or 13.56 MHz frequency band. The vessel antenna 206 is coupled with the vessel transceiver 208 demodulating the near field signal and extracting energy for supplying the vessel processor 210, the memory 212 and the display element 204 with energy (energy harvesting). The energy may be stored in a capacitor 213.

The vessel processor 210 decodes the information in the near field signal and displays the information on the display element 204. The information displayed on the display element 204 including, but not being limited to at least one LED, at least one OLED, a LED display, an OLED display, a display matrix, an e-paper, an electrophoretic e-paper, a liquid crystal e-paper, a bi-stable display, a bi-stable liquid crystal display. E-paper, electrophoretic e-paper, the bi-stable display and the bi-stable liquid crystal display have the advantage, that no energy is needed for displaying information on the display element, once the information has been updated on the display element 204. The information may be displayed as symbols, alphanumeric characters, colours, coloured icons or the like. If a single or small number of LED(s) or OLED(s) are used as display element 204, the information may be coded by the colour emitted by the LED(s) or OLED(s) and/or a flashing frequency of the LED(s) or OLED(s).

Since information relating to beverage is displayed in the display element after the near field signal has been received, the waiter and/or assistant can recognize the intended user of the portable beverage vessel. In other words, the information displayed on the display element 204 indicates, to which user the portable beverage vessel 200 has to be carried.

The display element may display an identification of the user who ordered the beverage. This allows to ensure that the beverage vessel 200 is assigned to the user who ordered the beverage. In case the assistant and/or waiter has supplied the beverage dispenser 100 with the order (information relating to beverage), the identification of the user on the display element 204 of the beverage vessel ensures that the beverage vessel is carried to the user, to whom the beverage is assigned. If the user has supplied the beverage dispenser 100 with the beverage order (information relating to the beverage) the identification of the user displayed on the display element 204 ensures that the beverage vessel cannot be confused with a beverage vessel of another user, if a plurality of beverage vessels are located in the same area, such as during a business meeting, during a break of team sports or the like. In both cases the information displayed on the display element 204 may also comprise the beverage recipe, a mineralization of water, a temperature of the beverage and the carbonization of the beverage dispensed into the portable beverage vessel 200.

Particularly in nursing environment transmitting the time stamp of the filling event to the vessel controller 202 and displaying the time stamp of the filling event is useful to monitor beverage consumption of patients. In other environments transmitting the time stamp of the filling event to the vessel controller 202 and displaying the time stamp of the filling event is useful to enable a user to determine the quality of the beverage.

The beverage vessel 200 may be a bottle, a carafe, a glass, a cup or the like. The container 201 may be made of glass, SiO2 or the like. The housing of the vessel controller 202 may be made of any suitable material such as metal, plastics, ceramics or the like.
